Abstract

The invention discloses a solar dehumidifying air conditioner system with an energy storage effect. The solar dehumidifying air conditioner system comprises a treatment air passage system, a regeneration air passage system and a solid dehumidifier energy storage bed, wherein the treatment air passage system and the regeneration air passage system are connected with each other through the solid dehumidifier energy storage bed. The solar dehumidifying air conditioner system has the advantages that the lower humidity and temperature can be realized under standard working conditions in summer, so the comfort requirement of an air conditioner is met; the humidifying and heating requirements can be realized by increasing the moisture content in the air under standard working conditions in winter; the requirements by insufficient radiation in rainy days and at night are met by the excessive energy stored in the solid dehumidifier energy storage bed in transition seasons; and the structure is simple, the easiness in control is realized, and the investment cost of equipment is low.

Description

technical field [0001] The invention relates to an air conditioner in the technical field of refrigeration and dehumidification, in particular to a solar dehumidification and air conditioning system with energy storage effect. Background technique [0002] The use of solar energy in air conditioning in summer is an important way to improve building comfort and energy saving. my country has a vast territory and is rich in solar energy resources. Using solar energy as a driving energy for air heat and humidity treatment is in line with the general trend of energy conservation, emission reduction and sustainable development in the current society. [0003] However, the use of solar energy also has the characteristics of unbalanced supply and demand: in summer, solar radiation is strong, and people have a large demand for dehumidification and cooling; Excess solar energy can be stored. If this part of excess radiation resources can be utilized, the utilization rate of solar en...
